be an order of magnitude greater than R1 and R2. The
current through R1 and R2 should be at least 1µA to
ensure that the 25nA (max) PFI input current does not
shift the trip point significantly. R3 should be larger than
10kΩ to prevent it from loading down the PFO pin.
Capacitor C1 adds noise rejection.

PROCESS: CMOS
The power-fail comparator can be used to monitor a
negative supply voltage using the circuit of Figure 8.
When the negative supply is valid, PFO is low. When
the negative supply voltage drops, PFO goes high. This
circuit’s accuracy is affected by the PFI threshold toler-
ance, the V
For noisy systems, bypass V
to GND.
